Here we have a case of the least common multipl(lcm) of 6 and 20.
Prime numbers 2,3,5,7,11,13,17,19... (natural numbers greater than 1 that has no positive divisors other than 1 and itself) .
lcm(6,20)= 6 20 | 2
                  3 10 | 3
                  1 10 | 2
                       5 | 5
                       1
2*3*2*5=60 The first one to get both calendar and the animal toy will be 60th.
 
Explenation: First we look for the smallest prime number with wich 6 and 20 can be devided by. That is 2. Next is 3. Since 10 is not divisible by 3, we only copy it. Under the 6 we got 1, wich is our goal. Now we continue to devide 10 by prime numbers till we also get 1. We now multiple all divisors and we get the least common multiple.

What are the factors of 3x²+7x-20?
Leya [2.2K]
3x^2+7x-20=0\\\\a=3;\ b=7;\ c=-20\\\\\Delta=b^2-4ac\\\\x_1=\frac{-b-\sqrt\Delta}{2a};\ x_2=\frac{-b+\sqrt\Delta}{2a}\\\\\Delta=7^2-4\cdot3\cdot(-20)=49+240=289;\ \sqrt\Delta=\sqrt{289}=17\\\\x_1=\frac{-7-17}{2\cdot3}=\frac{-24}{6}=-4;\ x_2=\frac{-7+17}{2\cdot3}=\frac{10}{6}=\frac{5}{3}\\\\\\3x^2+7x-20=3(x+4)(x-\frac{5}{3})\\\\\\3x^2+7x-20=0\iff x=-4\ \vee\ x=\frac{5}{3}

Help w all of these questions!!! aaahhhhh! you will be the brainiest and get 20 pts!!!!
erastovalidia [21]

Answer:

The answer to your question is below

Step-by-step explanation:

1.- 3x + 54 = 5x + 14

   3x - 5x = 14 - 54

   -2x = - 40

    x = 20

2.- I can not see it

3.- Yes, they are paralleles

because 180° = 119 + 61 = 180°

4.-

  180° - 82 - 31 = 67°

  180° - 67 - 98 = 15°

  q = 15°

5.- 100 - x + 30 + 4x + 7x = 180

     10x = 180 - 100 - 30

     10x = 50°

      x = 5

     7x = y

     y = 7(5)

    y = 35°

6.-

        55 + 4x + 2x - 5 = 180

        6x = 180 - 50

        6x = 130

        x = 21.7°

7.-

slope = (1 - 2) / (3 - 0)

     m = -1 / 3

     ( y + 1 ) = -1/3(x - 0)

8.-

9.-

slope = 3/7

P (-14 , -3)

   ( y + 3) = 3/7(x + 14)

10.-

Point (3,2)

A (2, 10)

B (4, 7)

slope = (7 - 10) / (4 - 2)

       m = -3/2

New slope = 2/3

            (y - 2) = 2/3(x - 3)
